Claims or reliefs affecting an earlier period - with QuickVid

Where a claim in a return reduces the Corporation Tax liability for an earlier period, you must tick box 45 on the CT600.

1. Open the Client setup section of the CTWizard and navigate to Repayment details under the Client setup section.

2. Tick the box for Repayment due for earlier period? to mark box 45 on the CT600.

3. To show the amount of trading loss carried back, complete the Carried back column in the Losses, deficits and excess amounts worksheet:

Note: HMRC confirmed in the following article that taxpayers can make such a claim when submitting their CT600 tax return for the period in which the loss is made. In some cases, taxpayers are being asked to submit an amendment for the earlier year or a letter to explain the repayment.
